THE NATURAL CHOICE IN ATTIC VENTILATIONThe 12-watt Solar Attic Fan is a simple and environmentally sensible solution that can save you money. Powered completely by free solar energy, this sleek and efficient vent is both compact and quiet.

Fully operational right from the box, it installs easily, with no electrical wiring, no expensive electrician and city permits. And it is powerful, operating at up to 850 cfm, a single unit can fully vent up to 1200 square feet. Place it wherever you need improved circulation; attics, lofts, workshops, storage sheds, garages, even barns.

Lowers attic temperature which can reduce the load on the HVAC (air conditioning) System. The most obvious reason for attic ventilation is to lower attic space temperature during the warmer months. Attic temperatures can exceed 160°F during hot summer days. Proper attic ventilation can reduce those temperatures by 50°F. Proper ventilation evacuates this excess heat build-up. As the heat is exhausted the work of the air conditioning system is reduced thereby saving energy and extending the life of the air conditioning system.

Extends the life of the roofing materials. Though asphalt shingles are designed to take the abuse of the sun for many years, they are subjected to greater temperatures when the roof decking is allowed to overheat, which is just what happens in an under ventilated attic.

In the cooler months, moisture is the most serious concern. Even with the use of vapor barriers to keep moisture from entering the attic, there are air leaks around ceiling light fixtures, bathroom exhaust fans that allow unwanted moisture into the attic. Moisture condensing on the framing members and the inside of the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing. A good indicator of moisture problem is rusty roof nails sticking through the roof deck.

Asphalt shingle manufacturers warranties require proper attic ventilation. Attic ventilation is required in cold environments-it evacuates the warm moist air that heat sources produce. Hot moist air lingering in the attic spaces can condense on the underside of the roof sheathing and rot it out and also causes mold to develop on the interior walls.

Good ventilation helps prevent ice dams, which begin to form when warm air in the attic melts the snow from beneath and creates runoff that refreezes on the colder eaves. An optional shut-off thermostat is available for colder climates.
